Pro Thermal 3 Headband - Men's

What Our Gearhead® Experts Are Saying:

"I add this under my helmet any time the morning temp drops below what my usual kit handles. The flat lock stitching means I never feel a seam, even three hours into a ride."

Castelli built this headband from Thermoflex fabric, a warm, soft, and stretchy material designed to seal the exposed strip between helmet and jacket collar without adding bulk under a shell. Flat lock stitching keeps the seams from digging in over long efforts, and reflective detailing on the back adds a margin of visibility for early starts.

This is the layer we reach for anytime the morning temperature dips below what a jacket alone can manage, small enough to disappear in a pocket once the sun comes up.
